AI Technical Summary

Benefits of technology

The patent text describes a mechanism for reducing vibrations caused by a rotating machine. A shutter flag is used to absorb the vibrations and prevent them from affecting the machine. The flag is placed between two parts and compressed to absorb the vibrations and prevent them from causing any damage. This mechanism can help to keep machines running smoothly and efficiently.

Problems solved by technology

One drawback to shutter actuation is that the shutter can generate audible noise as it is actuated.
In sound sensitive applications, the actuation noise of a calibration shutter can be a disadvantage.

Embodiment Construction

[0015]Reference will now be made to the drawings wherein like reference numerals identify similar structural features or aspects of the subject disclosure. For purposes of explanation and illustration, and not limitation, a partial view of an exemplary embodiment of a system in accordance with the disclosure is shown in FIG. 1 and is designated generally by reference character 100. Other embodiments of systems in accordance with the disclosure, or aspects thereof, are provided in FIGS. 2-5, as will be described. The systems and methods described herein can be used for reduced audible sound in shutter actuation for imaging systems.

[0016]The imaging device 10 includes a frame 102. An imaging sensor 104 is seated in the frame 102. A shutter 106 is pivotally mounted to the frame 102 by the motor hub system 100, which rotates along a rotation axis P (identified in FIG. 2). The shutter 106 is positioned to pivot between a first position that is clear of the imaging sensor 104, shown in so...

Abstract

A motor hub system for shutter actuation includes a shaft sleeve including a base flange and an externally threaded collet extending axially from the base flange along a rotation axis. A flanged nut with internal threads is in threaded engagement with the collet, wherein the internal threads are in a threaded portion of the flanged nut that extends axially from a flange of the flanged nut. A washer is compressed axially between the base flange of the shaft sleeve and the flange of the flanged nut.

Description

BACKGROUND OF THE INVENTION1. Field of the Invention[0001]The present disclosure relates to imaging systems, and more particularly to shutter actuation for imaging systems.2. Description of Related Art[0002]Imaging systems such as cameras utilize shutters to cover over the imaging sensor. In infrared imaging systems, calibration shutters are used to recalibrate the imaging sensor. In this context, a shutter covers the sensor and the sensor images the shutter. The shutter can be temperature controlled, or a sensor can be used to determine the temperature of the shutter. Using the known temperature of the calibration shutter allows the system to recalibrate the imaging sensor. If this is done periodically, the imaging sensor can stay well calibrated. One drawback to shutter actuation is that the shutter can generate audible noise as it is actuated. In sound sensitive applications, the actuation noise of a calibration shutter can be a disadvantage.[0003]The conventional techniques have...
